Frankly speaking, after the first month of ownership, I never try EV mode driving (almost forgotten about it.) Recently someone talking about A1 battery, then only I check on it.When you activate the EV mode, it read: EV mode currently unavailable.I sent the car back to SC, it was due to a weak A1 battery. The battery was replaced FOC as it is still under warranty. Do check on yours, of course, before warranty expires, or you pay RM400+.
